OIL TROUGH FOR INTERNAL-COMBUSTION ENGINES.

Application filed February 6, 1925. Serial No. 7,335.

To all whom it may concern: I

Be it known that I, PARKER B. I-IASKELL, a citizen of the United States of America, and a resident of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Oil Troughs for lnternal-Combustion Engines, of which the following is a specification.

This invention relates to oil troughs for integral combustion engines and has for its object the provision of means whereby the sediment in said troughs may be removed therefrom without disturbing the troughs or dismantling the casing.

These objects are attained by the inechanisin illustrated in-the accompanying drawings. f 1 I For. the purpose of illustratingthe .invention, one preferred form thereof is illustrated inthe drawings, this form having been found to give satisfactory and reliable results. although it is to be understood that the various instrumenta-lities of which the invention consists can be variously arranged and organized and the invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described except as required by the scope of the appended claims.

Of the drawings: 4

Figure 1 represents a vertical transverse section of a crank casing provided with splash troughs embodying thev principles of the present invention. v

Figure 2 represents a vertical section 01" a portion of the same on line 2 2 on Figure 1, and V Figure 3 represents a, section on line 3, 3.

on Fig. 2;

Similar characters 1nd1cate like partsthroughout the several figures of the drawings.

In the drawings, 1s a crank casing pro vided with a plurality of oil troughs 11 which as herein shown are formed integral with the casing but obviously could be made separate and installed therein;

Each trough 11. is provided with a compartment 12 containing oil through which the end of the crank 13 travels during each revolution of the shaft 14 to which said crank is secured.

The outer end of the crank 13 is pivotally connected to the connecting rod 15 and this pivotal connection 18 thoroughly lubricated as it passes through the o l in said compartment.

In the chamber 16 is positioned a cylindrical member 17 having a sediment pocket 18 which 1s adapted to register with the opening 19 at the bottom of the compartment 12.

Opposite the pocket 18-, the member 17 has formed therein a slot 20 extending lengthwise thereof and into which extends a pin 21 to prevent the rotation of said member.

The member 17 is provided with a cylindrical stem 22 at one end which extends I through an opening in a closure 23 which is threaded to the open end of the chamber 16 andis adapted to compress the packing ring 2 1 between it and the shoulder 25 on said member 17.

The inner end of the chamber 16 is" preferably closed except for the vent 26 through which the oil may escape when the member 17 is being inserted into said chamber 16.

To the outer end of the stem 22 secured a disk 27 by a screw 28, this disk extending beyond the periphery of said stem 22 and forming a means for retaining the closure upon said stem 22 when the member 17 is removed from the chamber 16. h

The troughs 11 are arranged in pairs with the closures 23 opposite each other and between the troughs of each pair there is formed in the wall of. the casing 10, an

opening 30 normally closed by a cover plate 31 secured to said wall by bolts 32.

lVhen it is desired to remove sediment from the troughs the cover plate 31 is re-.

returning it to its normal position.

During this operation the closure 23 is prevented from becoming displaced by the disk 27.

\Vhenever a plate31 is removed access is given to two members 17, it being under;- stood that there is an opening for eachpair of troughs.

By means of this construction the internal combustion engine of a fire truck may be kept in readiness to respond quickly to any call, for when it is necessary to clear the oil troughs of sediment this can be very quickly accomplished.

Heretofore it has been necessary to dismantle the crank casing and this takes a long time and as a consequence when the sediment is being removed from the troughs;

the fire truck is in unserviceable condition of each trough.

2. A crank casing provided with a plurality of splash troughs each having an oilcontaining compartment and a transverse chamber communicating with said compartment by an opening in the bottom thereof; a removable cylindrical member positioned in said chamber and having a sediment pocket therein in register with said opening; and means preventing the rotation of said member.

8. A crank casing provided with a plurality of splash troughs each having an oilcontaining compaitment and a transverse chamber communicating with said compartment; a removable cylindrical member positioned in said chamber and having a sediment pocket therein; means preventing the rotation of said member; and an opening in said crank casing giving access to said removable members.

l. A crank casing provided with a plurality of splash troughs each having an oilcontaining compartment and a transverse chamber beneath and communicating with Said compartment; a member in said chainher having a sediment pocket and a slot extending lengthwise thereof; a pin extending into said slot and preventing rotation of said member; and means for retaining said member in said chamber.

5. A crank casing provided with a plurality of splash troughs each having an oilcontaining compartment and a transverse chamber beneath and communicating with said compartment, said chamber being closed at one end; a member in said chamber having a sediment pocket and a slot extending lengthwise thereof; a pin extending into said slot and preventing rotation of said member; and means for retaining said member in said chamber.

6. A crank casing provided with a plu rality of splash troughs each having an oilcontaining compartment and a transverse chamber beneath and communicating with said compartment, said chamber closed at one end; a member in said chamber having a sediment pocket and a slot extend ing lengthwise thereof; a pin extending into said slot and preventing rotation of said member; and a closure for the open end of said chamber adapted to retain said member in said chamber.

7. A crank casing provided with a plurality of splash troughs each having an oilcontaining compartment and a transverse chamber beneath and communicating with said compartment; :1 member in said chamber having a sediment pocket and a cylindrical stem extending from one end thereof; and a closure for said chamber having an opening therein through which said stem extends.

8. A crank casing provided with a plu rality of splash troughs each having an oilcontaining compartment and a transverse chamber beneath and communicating with said compartment; a member in said chamber having a sediment pocket and a cylindrical stein extending from one end thereof; a closure for said chamber having an opening therein through which said stem extends; and means on the outer end of said stein for retaining said closure on said stem.
